To all whom it may concern: q

. Be it known thatjI, FRANK HINMAN PI ERL PONT, a citizen of the United States, residing at Horley, in the county ofSurrey,;England, 5 have invented certain new-and usefulImprovements in orRelating to Drilling or Like Machines; and .I'do-hereby declare the following to be a full, clear, and exactfdescription of the same, reference being had. to the '10 accompanying drawings, formingja part of this specificatiom and-to the letters of refer a a spring oneflend 'oflwhich is fastened to ence marked thereon.

The object of' th is inventionv is to provide a.

machine by which a cone-shaped or other hole I may be accurately positioned and formed in a body, such body being automatically fed into the machine and expelled therefrom into a receptacle after being operatedupon.

Although capable of more general application, the invention is primarilyintended for forming the cone-holein theend of a' rectangular matrix-blank, such as is employed ih'al Lanston monotype casting .and composing machine of the kind-described'in Patents Nos. 625,998 and 633,088, anda preferred con-- struction of a machine for this purpose will now be described with reference to the accompanying dra'wing's,fof which--., Figure l is a front elevationof the complete machine. Fig. :2 is a similar view, certain parts being cutaway. Fig. 3 is a section on the line 8 3 of Fig. 1 looking toward the left. Fig. 4 is a section on the l-ine lfl of Fig. 1 looking toward the right. Fig. 5 is an 3 5 end view of the revolving turret audits bed. Fig. 6 is a sideview of the spin'dle,-p'art being,

cut away, together with a' s'ection of the. turret, showing one of theblank-holders therein.

Figs. 7. and 8 are end views ofltliesamewhen' 4o stationary and when revolving, respectively. Fig. 9 is a view in perspective of the spindle detached. Figs. lOand.l1 are detail views of the spindle-clutchfrnechanism:- Figs.'12, 13, and 14. aredetail views of part of the delivery mechanism, and Fig.. 15 shows a matrix-blank in perspective and in longitudinal section.

Like letters indicate like partsin all the figures.

Revolubiy carried in bearings in a block A is a hollow spindle B, ,onto which is rigidly fixed,by means of a set-screw C-,a clutch-body O. The clutch-bo yahas a coned-friction-surface C at one endand a screw-thread. at the other, on which isengaged a sleeve C having a second coned surface 0 set-screw O, and around its, free end is coiled the said sleeve, the otherv to the'set-screw- O in such a manner that the tension of the The sleeve O is provided with a ,slot ,C to receive the spring tends to screw the sleeve farther onto the clutch-body, bringthefset-screw C toward'the left-hand end of;tl1'eslot,looking at Fig. 11, and cause thefriction-surfaces C O to engage corresponding. surfaces on a pulley C, loosely carriedfon theclutch-body: The pulley O is constantly-{revolved byany con- Venient source of 'power. The sleeve 0 is also provided with an offset 0 and a catch 0 carried on an arm 1) on a rock-shaft D, is normally adapted to engage this offset undertension of the curved spring D When the clutch-sleeve is thus held, the friction-surfaces of the pulley still carry the clutch-body around until the set-screwQ. engages-the righthand end of the slot, (looking at Fig. 11,) when the set screw and with it 'the clutch-body and the spindle are arrested. At the same time the clutch and pulley, friction-surfaces have become so far disengaged as" merely to The spindle-head B (shown in Fig. Sand detached in Fig. 9) for. carryingthematrixblank is screwed into theholiow spindle B.

maintain the spindle constantly in the one ,position Without risk of 'overstrain to any part of the machine.

lindrical body E of a revolving turret. The Y bodyEis capable both of revolving within.

the casing and of a reciprocating .motion in the direction of its axis. It extends beyond the casing, and its back end is provided with a flange E from which projects an annulus E Fixed on the end of the bed-plate A, so as to be positioned behind the turret, is a standard A, having a curved guideway A circular or oval in cross-section, in which is engaged the similarly-shaped head of a pin F*. This pin is telescoped into the end of a handle F, pivotally secured to a pin F, placed centrally in the back end of the turret-body E. The handle is secured to the pin F by studs F engaged in a groove F Figs. 1 and 5, so that the handle is capable both of revolving around the pin and of a swinging movement thereon in the plane of its axis. Carried in an offset of the handle F is a fiat-headed stud F the head of which is held by the tension of a spring F in contact with the external periphery of the annulus FE. This peripheral surface is formed with a series of eccentric curves, the highest portion of each curve joining the lowest portion of the adjacent curve by a steep fall, providing a series of catches E. Itis evident that if the handle F be pulled to the left in the direction of the arrow in Fig. 1 and then in the reverse direction the turret IE will be reciprocated within its casing E in the line of its axis. If the handle be pulled in the direction of the arrow y in Fig. 5, the pin F will slip along the surface of the annulus, the handle rotating around its carrying-pin F. If, however, the motion of the handle be reversed, the pin F, engaging one of the catches E will rotate the turret within its casing in the direction of the arrow (1;, Fig. 5.

Arranged on the front face of the turret E are two compartments E E", each exactly proportioned to hold one of the matrix-blanks. These compartments maybe formed directly in the turret-body, and preferably they are formed of hardened-steel plugs held in position by set-screws, as shown in Fig. 5. Two holes E E are likewise provided to hold cutting-tools. The compartments E Eand holes E E are arranged on the circumference of an imaginary circle concentric with the turret-body and so placed that as the body is revolved they coincide one by one with the compartment 13 of the revolving spindle, before described.

Cut in the edge of the flange E are four slots F. F. E 13, one corresponding to each compartment E E and tool-hole E E respectively, and carried in a lug on the casing E is a flat pin E adapted to fit in said slots when the turret is in its forward position, the pin and slots being so positioned that when the pin is engaged in any one of the four slots either one of the compartments or one of the tools shall accurately correspond with the matrix-holding compartment of the revolving spindle.

The two compartments WE are continued back through the body of the turret by round teases holes, in each of which is an ejecting-rod E".

These two rods are connected within the annulus by a cross-bar E, with which is engaged one end of a lever E pivoted by a pin E in lugs of the flange E The other end of the lever extends through a slot in the annulus E in line with the slot E so that when the pin E enters the latter slot the rods E are pushed into the compartments E E and eject the matrix-blanks seated therein.

It will be remembered that the catch G which engages the offset of the sleeve portion of the rcvolnble spindle-clutch, is carried on an arm D, fixed on one end of the rocking shaft D. This shaft is carried in bearings in a bracket A and in a lug E on the casing E and has a second arm D on the free end of which is a short cross-bar D which engages the periphery of the flange in all positions of the turret in its casing. This periphery forms a cam-curve, the lowest portion of which extends from the steep fall at c, Fig. 4., to z in the direction of the arrow and is coincident with the compart ments E and E, while a sudden rise in the curve commences at ,e" and continues on to the fall at 5. When the cross-bar is engaged with the lower portion of the curve, the catch C is engaged with the offset 0 of the clutch and the spindle is stationary. The rise in the curve, however, throws back the arm D against the tension of the spring D releases the offset, and allows the clutch to act, revolving the spindle.

The devices for supplying the blanks to the turret and for ejecting them from the machine after being operated upon are carried, respectively, on standards A A on opposite sides of the bed A. These standards are preferably formed, as shown in Fig. 3, in one casting, being connected by a web.

Preferably the blanks are fed to the ma chine from a stick or galley consisting of a long case G, in which the blanks, placed side by side, are an easy fit. Conveniently the case is open down one side, so as to readily show the number of blanks therein, and it is open at each end, a catch G, Figs. 13 and 14, pivoted at G so as to be under tension of a spring G engaging the last matrix when the case is free.

The case is held in an approximately yer.- tieal position in a guideway A on the standard A This guideway ends in a short race G'flwith an opening G at its lowerend. The guideway A is closed over at its lower end by a plate A, which when the case is placed in position, pressing against the head G of the spring-catch, forces the latter up, freeing the blanks, which fall by their own weight into the raceway. The spring-catch G thus also serves to hold the case firmly in the guideway.

The face of the opening G is in the same vertical plane as the face of the matrix-blank compartment of the revolving spindle and is so positioned as to coincide with the blankthe lever engaging the revoluble spindletal position and is formed wit-h or fixed onto compartment of the turret when the compartment E coincides with the spindle-com- .partment, which is the receiving position of the turret and is shown in Fig. 4:. To eject the blank from the raceway, a short rod G (best seen in Fig. 2) is provided, carried in a lug on the standard A The rod has a slotted head, within which isengaged the head.

of a lever G pivoted at G and having its other head engaged in a slot G in a collar fixed on a shaft H. This shaft is carried in bearings on the standard A and on the easingE and extends inpne direction to just behind the said casing, so as to engage the flange E of the turret and be moved forward when the latter is advanced. A screw-pin H, with a lock-nut, is preferably provided to.

engage the shaft, so as to be able to regulate the degree of movement of the same. The other end of theIshaftI-I engages the headof a lever B, pivoted at B in lugs on' a block A, fixed on the bed A, the other head of ejecting rod' B A similar arrangement of guideway and case to that above described is provided to receive the. blanks after being operated upon. This guideway A however, is in a horizon the standard A Fig. 3;. It ends in a raceway J, (best seen detached in Figs. 13, ll,

and"15,) the free end of which has a side opening J to receive the blank'from the turret. The face of this opening is in the same vertical plane as those. of the'delivery-race and spindle and coincides in position with the compartment E of the turret when the latter has been revolved from thereceivingposition, asshown in Fig. at, to theejecting p0 sitionthat is, when the compartment F. has been brought to the position occupied by E inFig. 4. The position of the guide rela tively to the turret and its casing'is shown in dotted lines in Fig. 4. I

In order to drive the blank when received from the turret into the case or galley G, the end of the race J is slotted to'receive an ejecting-blade J having ahead J provided with a beveled surface. in the face of the turret Eas to engage the beveled'surface of the head and drive the blade into the race once during each complete revolution of the turret, forcing the blank last received into the position shown in Fig. 14 and leaving the opening clear to receive anotherblank. The blank when thus driven forward is held by the tension of a springJ engaging the blank when thus pushed in to prevent any danger of its posi-' tion being accidentally shifted by vibration.

The ejecting-blade is held between guideplates extending from the race J andis normally held out of the raceby a coiled spring J, Fig. 12, a pin J Figs. 13 and 14, engaged in'a slot in one of the guide-plates, limiting the action of the spring.

A pin J is so'positioned Although not found in practice to be generallynecessary, itis desirable in some cases to provide means to prevent the blankslip ping out of thespin'dle matrix-compartment when the spindle is revolving. For this purpose, as shownin the figures, a cap B is providedwhich has an opening B in its crown,

(similar in shape to the matrix-compartment of the spindle-head,) which screws onto a threaded portion of the spindle-head B, Fig. 6. A spring B one end of which is fixedjon the spindle-head and other onto the cap, is so arrangedas' to tension that it normally holds 7 the opening 13 out of coincidence Withthe matrix-compartment, as shown-in Fig. .8.

The cap 13 is provided with an offset B.

It will be remembered-that the shaft D is rocked by the cam-surface of the turret-, flange, so that the armD engages the catch C 'with and disengages it froinltheclutch The shaft D is provided with another arm D which is adapted to engage the offset B? synchronously with the engagement of the clutch and consequent stoppageof'the spindle revolution. The offset B is so positioned on the cap relatively to the rock-shaft arm thatthe a isarrested, with its opening B in correspondence with the blank-compartment of the spindle, as'shown in Fig. 7. A blank; can therefore enter or leave the spindle-head While the spindle is stationary; but directly the spindle is revolved the matrix-compartmentis partially blocked. V

A pin B Fig. 9, may be provided to prevent the cap-face pressing dead against the face of the'spindle-head. n 7

Set-pins E wit-hlOck-nuts, may be provided in the flange E for the purposeof regulating the exact position to which the turret .is advanced, and holes H are formed there in, through which the rod H passeslwhenthe turret'is'advancedat other than the delivery position. e v

' The operation of the machine is as follows: In Figs. 1 to 5 the various parts of. the .ma}.

chine are shown .in the position they occupy I at the commencement of a fresh revolution of the turret, when a blank is inthe bottom of the feeding-race G and ablank, with the cone already formedfln the spindle compart- The .pin E is opposite the slot E which positions the compartments E and, E

ment B opposite the compartments of the race and of y the spindle, respectively. The barD offthe arm D is engaged with the lower curve of.

the flange-cam. Consequently the catch C is engaged with the offset O (see Fig. 7,) and the spindle is consequently stationary- The f handle F. is now pulled in'the directionv of the arrow, Fig. 1, and the turret advanced. The rod I-I coming in contact with its pin H is driven toward the left, and the lovers G7 B drive the ejecting-rods G B respectively, to-

ward the right, Fig. 2, pushing the matrix-, blanks from the race and spindle-head into the turret compartments E E respectively.

The handle is now reversed and the turretbody drawn back toits first position, as shown in Figs. land 2. Looking now at Fig. 5, it will be seen that the pin F of the handle is close to one of the catches E of the annulus. Pulling the handle, therefore, toward the left, Fig. 5, the turret is revolved within its casing until the pin E coincides with the next slot E. The compartment now is coincident with the spindle-compartment and E with the delivery-race opening J. The turret is now again advanced, and as the pin E enters the slot E? it engages the head of the lever E, which drives forward the two ejecting-rods E and pushes the blanks from the compartments E E into the spindle-compartment and race J, respectively. In entering the spindle-compartment the blank pushes out the ejecting-rod 13', (which had remained therein after ejecting the blank,) and through the lever B thereby restores the shaft H to its normal position and withdraws the ejecting-rod from the race G, allowinga fresh blank to fall to the bottom of the same. During these operations the bar D" has been engaged with the lower portion of the camcurve and the clutch consequently out of action. The turret is again drawn back and then revolved until the slot E is opposite the pin E. The bar D has now passed the line .2, Fig. 4, and is engaged with the higher portion of the cam-curve, the shaft D has been rocked,the clutch'o ffset disengaged from the catch O and the spindle revolves. The tool in the hole E is now opposite the spindle-matrix compartment. The turret is advanced and the tool operates to roughly form the cone. The turret is drawn back and then revolved till the slot E is opposite the pin E bringing the second tool opposite the spindle-compartment. The turretis again advanced, and this tool completes the formation of the cone and the turret is again drawn back. The turret is now revolved, bringing the slot E opposite the pin 'E that is, to the position shown in Fig. 4, with which this description of the operation commenced. The bar D has now again reached the lower portion of the cam-curve, the shaft D has been rocked, and the catch 0 engaging the clutch-sleeve offset C arrested the revolutions of the spindle. The pin J which operates the ejection-blade J of the deliveryrace, preferably acts on the same simultaneously with the placing of the blanks in the turret-compartments.

Although only two tools are mentioned in 7 this description it isevident that more than two may be employed if desired, an additional slot to engage the pin E of the casing being provided for each additional tool.

It is evident that the cases G may be dispensed with, a long delivery-race G being provided into which the blanks are directly placed, while the blanks may be ejected from the raceJ into any desired form of receptacle.
